SCHUNK has updated its Tendo Slim 4ax hydraulic expansion toolholder device with "cool-flow" technology, for effective cooling via tool mountings. Introduced three years ago, the Tendo Slim 4ax has the outside geometry of heat-shrinking mountings, according to DIN 69882-8, with Schunk's proven hydraulic expansion technology.
In contrast to heat-shrinking toolholders, the Tendo Slim 4ax seamlessly fits into Schunk's hydraulic expansion technology with its permanently precise run-out accuracy of < 0.003 mm at an unclamped length of 2.5 x D, and a balancing grade of G 2.5 at 25,000 RPM.
Moreover, the shape and positional tolerances can be met with accuracy.
Since the precision mounting of conventional heat shrinking toolholders can be replaced by Plug-&-Work without having to reprogram the outside contour, their advantages can be directly tested or permanently used.
The slim mounting with cool-flow technology will be available in 90-mm and 120-mm lengths for the HSK-A63 interfaces between ø 6 mm, up to ø 32 mm. The interfaces for SK 40 with ø 6 mm up to ø 32 mm will be available in mid-2020. Other interfaces, such as BT 40 and length variants with 160 mm, are being planned. Learn more at www.schunk.com
